GAS-HOLDER.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed M3122. 1905. Serial'No. 261-636.

To all whom it may concern: Be it known that I, HENRY A. CARPENTER, l a citizen of the United States, residing at State of Pennsylvania, have invented a new and useful Improvement in Gas-Holders, of which improvement the following is a specification.

My invention relates to certain new and useful improvements in gas holder construction, the object of my invention being to provide means for more efficiently stiffening the different lifts which comprise the holder, and to so dispose the stiffening means with relation to the lifts as to make the portions or parts of the lifts, between which the seal is formed, when one or more of said lifts are elevated, more rigid and secure than has been possible in previous constructions.

My invention although not limited to gas holders of any given size, is especially applicable to gas holders of large dimensions, in which a number of lifts are used.

In describing my invention I will refer to the accompanying drawings, forming part hereof, in whichthe figure indicates a sectional elevation of one side of the several lifts comprising the gas holder, a portion Referring to said drawings, 1, 2, 3, 4, and 5 are the several lifts, or sections of the gas holder, to the upper portion of which goose neck or guide roll supports 6 are secured.

In the outer ends of these supports 6, respectively, are secured blocks 7, in which the radially disposed guide rolls 8 and the tangentially disposed guide rolls 9 are mounted, and are adapted to travel on the vertically disposed guide 10, as the said several lifts are elevated and lowered. In addition to said rolls 8 and 9, a roll 11 is mounted, in the lower portions of each of said lifts, as an ad ditional means of guiding the same and rolls 12 may be applied as further guides for the inner lifts. Pockets or annular receptacles 18 are formed in the outer lower portion of the several lifts, into which downwardly eX- tending projections 14, formed on the inner upper portions of the adjacent lifts are adapted to project; the pockets being filled I with a liquid, a seal is formed between the several lifts or sections when the same are elevated.

My improved method of forming the pockets 13, and of securing the projections 14, to

the several lifts, consists in securing two or more channel, I, orother suitable beams 15, to the upper inside, and lower outside of the several lifts, the said beams being arranged some distance apart, with their flanges o positely disposed and secured to the p ates The plates 16 which are secured to the lower set of beams form a pocket between said plate and the lifts, and the plate 14 secured to the upper set of beams forms a projection which projects into the pocket in the next adjacent lift to form a liquid seal as heretofore stated.

The construction described not only stiffens and makes the sectional holder more rigid, but also forms a complete double joint at both the upper and lower portions of the seal formed between the several lifts, thus reducing the liability to leakage. The chambers formed by the respective pairs of beams 15 may be filled with mineral wool or other suitable substance to still further decrease the liability to leakage.

I claim as; my invention and desire to secure by Letters Patent:

1. In a gas holder, the combination with the several lifts, of a plurality of beams secured to the periphery thereof at their lower ends, an annular member secured to the outer side of said beams for forming an annular pocket at the lower outside of the lifts, a plurality of annular beams secured to the inner upper portion of the lifts, a plate secured to said beams, said plate being adapted to enter the pocket formed at the outer 'lower portion of the adjacent lift when the same is elevated.

2. In a gas holder, the combination with the lifts thereof having annular pockets at their lower portions, of a plurality of reinforcing beams secured to the upper portions of said lifts, and downwardly. extending members secured to said beams and forming projections adapted to enter the pockets at I the lower portions of the lifts when the latter are elevated. V

3. In a gas holder, the combination with the lifts, of a plurality of beams secured to the periphery of the lower end of each of the lifts and spaced apart to form chambers, members secured to the outer sides of said beams for forming pockets at the lower outside of the lifts, a plurality of beams secured to the inner upper portions of the lifts, and

members secured to the inner sides of said 1 beams secured to the inner upper portions beams and forming projections adapted to I of the lifts and downwardly-extendingpor-vl enter the pockets formed at the outer lower tions secured to the inner sides of said beams portions of the lifts when the latter are I and forming projections adapted to enter elevated. the pockets formed at the outer lower por- 4. In a gas holder, the combination with I tions of the lifts when the latter are elevated. r

the lifts, of a plurality of horizontally-(Esq posed outwardly-extendingreinforcingbeams secured to the periphery of the lower portion of each of the lifts, members secured. to the outer sides of said beams for forming pockets at the lower outside of the lifts, a plurality of horizontally-disposed inwardly-extending In testimony whereof, I have hereunto scribing witnesses.
